DOORLATCH Filed NOV. 8, 1954 Patented Aug.Y 6,l 1935 f UNITED STATESPATENT OFFICE 1 Claim.

This invention relates to door latches and the general object of thelinvention is to provide a door latch of an extremely simpleconstruction which may be readily applied to a door and which l isextremely cheap to manufacture.

My invention is illustrated in the accompanying drawing, whereim- Figurel is a vertical fragmentary section through a door showing my latchapplied thereto, the latch being in elevation.

igure 2 is a horizontal section through a door and door jarnb showingthe latch in plan View, the handle 2t being in section.

Referring to the drawing, l@ and il designate two opposed platesdesigned to go on each side of a door and be held in place thereon bythe half inch bolts I2, carrying thereon the nuts i3. These plates leand l l are slotted for the passage of the lever latch M, this latchmember being pivoted upon a transversely extending pin I5, extendingthrough the latch I4 and extending through openings in the heads of thebolts I2. This pin I5 constitutes a pivot pin for the latch This latchat one end is curved in one direction, as at I6, to form a handle and atthe other end beyond the plate ll, the latch is connected to aretractile spring l'i in turn connected to an end of a bolt it whichextends through the upper ends of the plates lil and II. One edge faceof the latch facing the door frame beyond the plate It is formed with anotch i9, one wall of which extends inwardly on an incline from the edgeface of the latch so that this notch is ratchetshaped.

Extending over the opposite end of the latch is a guard 2t, which isapproximately U-shaped and made of a strip oi metal, this guard beingturned inward at its ends, as at 2 I, and these ends being apertured forthe passage of the bolts I2, the nuts I3 bearing lagainst these inturnedends of the guard.

C'oacting with the latch I4 is a keeper plate 2?. adapted to be attachedto the jamh of the door by screws 23. The end wall of the notch i3 isada-pt- 5 ed to engage over the corner Eil of this keeper.

It will be seen, of course, that the spring I'I urges the notched end ofthe latch downward and that as the door closes the latch will ride upover the corner 2li of the keeper .22 and then fall into place A10behind the keeper, latching the door closed. vBy i lifting the end ofthe latch i6 or depressing the opposite end of the latch, the door maybe opened.

It will be seen that the latch is composed of Very few pieces and thesevery cheaply made and that the latch is very simple to operate.

It will he seen that the guard 2t constitutes a handle for the door andat the same time it acts as a guard to prevent stock from working thelatch and opening the door as they do in many makes of latches. When,however, the operator grasps the handle the ngers naturally push againstthe shank I4 to open the latch.

What I claim is:- 25

A latching structure of the character described, comprising opposed doorclamping plates, bolts passing through the plates and adapted to passthrough the door, the plates being slotted, a latch having a shankextending through the slots, a pivot pin upon which the latch is mountedhaving its ends extending through the bolts, a spring engaging the latchat one end and urging the other end of the latch downward, the lastnamed end of the latch havingY on its under face a ratchet-shaped notchto engage over a keeper and a U-shaped guard extending around theopposite end of the latch from the notch and having inwardly extendingends through which the bolts pass.

HORACE R. JONES.
